Rainbow lashes are the perfect way to add sunshine to your look

The female population of Love Island may disagree on this one, but long, hot summer days and an overload of make-up are not happy bedfellows.

When it’s too hot to handle, minimal fuss is not just an attractive proposition but a basic requirement. But, for the days capable of melting your foundation to an oil slick and turning lipstick into a chore, there is a fast yet effective way to brighten up your beauty look — a coloured mascara.

Bold, bespoke and guaranteed to take no more than 15 seconds of time that could be spent basking in the sun, the best thing about a statement mascara is that it’s most effective when paired with an otherwise bare face. Plus, there are countless ways to experiment, too.

Navy is a good entry-level shade that is universally flattering to all eye colours, while bolder blues such as teal or turquoise will also help counteract any redness to make your eyes look whiter and brighter.

As for more vibrant and unusual colours such as flamingo pink or sunflower yellow, try easing yourself in by layering over a slick of your fail-safe black for a more subtle tint.

Fun and affordable cosmetics brand 3INA is a good place to start your search. Its vegan, paraben- and cruelty-free colour mascaras are a bestseller and available in shades from forest green to fuchsia. For lovers of luxury, YSL’s popular Mascara Vinyl Couture  comes in high-pigment hues spanning aubergine to cobalt, as well as gold, designed to be worn as a top coat.

Nars’s Audacious mascara  also features more than 200 bristles to coat even the tiniest lashes in colour — try its amethyst Park City shade, designed to complement green or hazel eyes — while Crayola’s collaboration with ASOS includes mascara  in a paint box of shades so you can always look on the bright side.
